Unfortunately the bitcoin price does affect me financially even if I'm a long term hodler.
I'm not sure I understand what you meant with regards to mining. I was a bitcoin miner for about 6 months in 2013-2014 and the reason I stopped was because it was cheaper to buy bitcoin than to mine it.
As the price of bitcoin goes down to a level that it becomes cheaper to buy bitcoin on the exchange (a small mining farm has different cost structure than a big mining farm), the machines will be physically shut down, thus causing the difficulty to go down (the bitcoin software protocols readjust difficulty every 10 days based on the network hashrate to keep the block frequency at a target time of 10 minutes). When bitcoin price goes up, the miners will be powered back on.
all this stuff about mining, plus the lightening network, etc... are just smoke and mirror stuff that the whales put in front of the public as distractions.
none of this stuff matters. we've discussed before.. it's a scam...I'd pull money out and buy some real stuff like the qqq.
